KMS Performance

Best tuner in town by far. Kelly is a magician. Thanks buddy for everything you guys do for Gravity Motorsports.

I first started shopping for an X3 a few weeks ago. I literally looked at every X3 listed for sale on CL / FB marketplace during that time frame. At least a third of the private sellers and dealers too I met with mentioned Kelly's name and his shop, KMS Performance. I naturally started to look into the ECU / clutch tuning work that Kelly did. I noticed tons of great reviews. Kelly spent a good 30 minutes on the phone with me the first time we spoke, explaining his processes for tuning. Everything he said made total sense. Kelly offered pick up / delivery services as well as part of the tuning fee. I ended up getting my X3 dropped off at Kelly's shop on a Sunday. Kelly went out of his way to open up his shop to be able to receive the X3 over the weekend - WOW! The ECU / clutch tuning work was done the very next day. I received follow up communication every step of the way. I received before/after dyno graphs for torque and horsepower. Kelly even dropped the X3 off at the next shop, so I could get my Rugged radio installed. It was so nice to not have to worry about picking up / dropping off my car at the next shop. It saved me at least 4 hours out of my day. What an amazing experience! I wish every shop I took my vehicles to performed as good customer service as KMS Performance! Thanks, Kelly!

Kelly is the man when it comes to performance modifications on a UTV. He tackled a complex engine by another very reputable builder from out of state. After he worked it over not only is it significantly more powerful than before, but it starts, runs and sounds better. I just think his level of understanding is above most of the engine builders when it comes to performance machines. He is also very helpful when trying to drop off and pick up. It is well worth the two hour drive to his shop.

Hands down the best performing tune and clutch work I have had. Kelly and his crew know what they’re doing and their customer service has been good each time I’ve had questions. I would highly recommend!

Kelly has done a great job tuning my car thru various upgrades. Currently building my yxz engine. He takes the time to answer any questions you have to put you in the right direction for your build.

Very happy I went to KMS. Kelly knows it all when it comes to tuning. He explained everything that he did on my rzr. Best money I ever spent on a vehicle, and I've been playing in the dirt for quite a while. My first ride at the dunes was a Honda 90 three wheeler. Lol Definitely recommend Kelly and KMS. D. Arnold

KMS gave away a billet intake plenum for a Honda Talon at UTV Invasion. My ticket was drawn. I dont own a Honda Talon. They had no problems trading it for something for my CanAm X3. Once I decided on a quick change belt tool, the wrote down my info and immediately emailed their warehouse packaging personell with me cc'd. It only took a week and they covered shipping. If they handle stuff they are giving away with this much care and detail. Im sure they take pride and the care in the stuff they do sell. Ill definetly keep my eye on these guys in future purchases.

Kelly of KMS is the genius of tuning motors. Motorcycle's, Off-road etc. This guy git my M109R Boulevard Cruiser tuned on the money.

Kelly is amazing. Tuned our rzr 1000 big bore. Did an amazing job. He is extremly knowledgeable. All my friends are amazed by our rzr now. Kelly was recommended by Nate at Alba racing in California. And that alone says alot. If u want more reliable horsepower go to KMS. Kelly, thanks
